Claims, one by one

The text below is copied verbatim from the published record. Each claim names the source dossiers that carry it; caveats stay attached to the claim they qualify.

Claim 1 clm-e1e050f4759a8434 quantitative

a 2025 study links the camera programme to a significant fall in pedestrian robbery (2018-2019 data)

Published field: impact · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: The impact itself describes the peer-reviewed findings as split.
Caveat: A 2023 study found no effect on delivery robberies from the 2019 MiCalle expansion, and police use camera footage in under 1% of investigations.
